r This inventionrelatesto pressure valve attachments. a j 1 In my copendingapplication entitled Humidifying device, filed February 28th, 1933, bearing ,1 Serial N0. 658,901, Ihave'describedandclaimed a. humidifiercooperating with a radiatorheating system of the regulation or other approved hot waterysteam or other suitable type, comprising ingeneral a hollowheating element arranged to if) be conneoted with the: interior, specifically the interior of an end radiator unit, of a regulation radiator, .a casing for containing water in heat exchange contact with the hollow heating; element, and other appurtenant parts.

The present invention comprises means of general hollow constructionarranged vto be interposed between the interior of the, radiator and the hollow heating element, particularly for; a radiator or heatingsystem employing steam or a equivalent as the heating medium, the sameineluding or providingfor theconnection there with of an air valveforautomatic venting purposes.

; H My.;i1 1vention is? applicable with the employ-1 T merit; of devicesqother than humidifiers: in con nection fwith aradi-ator or equivalent heating More particularly, my invention is directed to a member, advantageously a,v casting, comprising atone side'a nipple, element, preferably threaded and adapted to beconnec-tedwith the usual threaded; opening leading to the interior of a radiator unit, and further comprising an opening for the reception of a regulation or other approved air valve, and further comprising a nipple element for a direct connection with or indirect connection through piping leading to one end of a hollow heating element or other hollow element of a device communicatively associated with the radiator.

Further features and objects of my invention will be more fully understood from the following detail description and the accompanyin drawings, in which i Fig. 1 is a side elevation of a preferred embodiment of my invention, illustrated in operative connection with an end unit of a radiator, partially illustrated, and a humidifier, the lastnamed being illustrated in central vertical sec- L tion;

Fig. 2 is a vertical sectional elevation on line 2-2 of Fig. 1, on an enlarged scale; and

Fig. 3 is a sectional elevation online 3-3 of Fig. 2.

Referring to the drawings, the radiator is in- .the end unit thereof is indicated 11.

dicated generally by the reference number At 12, 13 are indicated the regulation threaded openings of a regulationradiator unit. 1 v

The humidifier 14 typical of a device communicatively] associated with the radiator, as il lustrated, comprises a hollow heating element 15, illustrated in the form of a section of a fin tubing, the lower end of which is connected to a header 16, preferably having a threaded nipple or other suitable termination 17 arranged for connection, as by means of tubing 18, and pressurecouplings '19, 20, for communication with the interior of a radiator 10, or unit thereof 11; as shown in Fig. l the communication is effected through the attachment means 21, described more fully hereinafter.

The upper portion of, the heating element is shown provided witha header 22 having a threaded nipple or other suitable termination 23 arranged for communicative connection with the interior of a radiator 10, or, unit thereof 11, as by means of piping 24 and pressure couplings 25, 26, supplemented if desirable or necessary with the reversely threaded nipple 27. k I- 'More particularly, the embodiment of myattachment means, see Figs. 1, v2 and 3', comprises a hollow ,body 30, shown in the form of a casting, having at its one verticalface a threaded nipple or other suitable termination 31, preferably integral therewith, arranged tobe threadedly connected inthe opening 12' of the end radiator unit 11. The body is also provided with the threaded opening 32, or equivalent, for suitable connection with the illustrated lower end of the piping 18, namely, by means of a threaded nipple 33.

The body 30 is further provided with a threaded or other suitable opening 34 attachment to receive the threaded nipple or other suitable termination 35 of a regulation or other suitable automatic air venting valve 36.

The configuration of the hollow body 30 is shown particularly designed for cooperating with a drain tubing 37 of a regulation air release valve 36, and it is understood that the body 30 may be varied in configuration and detail construction to accord with the assembly of any particular air release valve or equivalent device employed therei with.

Advantageously, the nipples 31, 32 are positioned on opposite faces of the body 30 and the opening 34 on a face lateral in common to such opposite faces. Specifically, as illustrated, such laterally common face is substantially at right angles to such opposite faces, thereby enabling of the air release valve 36 in placing in posi the airrelease valve 36 to be placed in or removed from position by rotative movement, without encountering obstruction either by engagement with the radiator unit 11 or the humidifier or otherwise.

As appears, the vertical dimension of the interior of the body 30 is designed in general to accommodate the drain tube 37 of the illustratedair release valve 36, such drain tube 37 usually depending freely from the threaded nipple portion 35. Accordingly, upon rotation of the body tion or removing from position relative to the threaded opening 34, the drain tube 37 is ac'com modated within the interior of the hollow body 30.

The nipple 31, in fulfilling its function of drainage by gravity, is advantageously located at substantially the lowermost position with respect tov steam enters the nipple 31' within the body 30,

thence through the nipple 33, piping 18, nipple 17, lower header 16, into the heater element 15, and, possibly, also through the upper header 22, piping 24', in return to theinterior of the radiator 10, whereby water 40 placed within the casing 14 of the humidifier is evaporated by the heat units exchanged through-the intermediation of the heater element 15. Water resulting from the condensation of steam in the heater element 15, flows under gravity into the lower header 16, pip ing 18, thence within and through the hollow interior of the body 30, and ultimately through the nipple 31 into the radiator 10 and the piping connected therewith. Automatic venting of any air entrapped within the above stated parts is effected by the regulationor other approved automatic air vent device 36, any liquid condensed within theair" vent device 36 discharging through its tube element 37 into the interior of the hollow body 30 and thus through the nipple 31.

Whereas I have described my invention by reference to specific forms thereof, it will be underrelease device further comprising an opening arrangedffor connection with an air release valve communicating with the interior of the device at a location above the stated region of communication of said lowerly disposed nipple portion, the

air release device further comprising an opening .communicating with the interior of its hollow body at a location above the stated region of communication of'saidlowerly' disposed nipple portion, said second named opening being arranged for connection and communication with a lowerly portion of the heater element of the humidifier, the upper portion of the heater element-of the humidifier being connected with the interior of the radiator. r

2. An air release device for an associated heating radiator and a therewith connected humidifier provided with a heater unit, the air release device comprising a hollow body provided with a nipple portion communicating with a lowerportion of the interior of the hollow body, the said nipple portion being arranged to be connected with the radiator through a port in the radiator, said air release device further comprising an opening arranged for connection with an air release valve communicating with the interior of the device at a location above the stated region of communication of said lowerly disposed nipple portion,-the air release device further comprising an opening communicating with the interior of its hollow body at a region above the stated region of communication of said lowerly disposednipple portion and below the stated region of'comrnunioation of said first named opening, said second named opening being arranged for connection and communication with a lowerly portion of the heater element ofithe humidifier, the upper portion of the heater element of the humidifier being connected with the interior of the radiator.
